As for the sleep thing...

I recently read The Dragons of Eden by Sagan about the evolution of the human brain. He goes into sleep a little and although im a bit shady on the details he talks about how sleep is probably a leftover advantage of our ape/early hominid ancestors. Sleeping at night prob gave some protection against their predators. He talks about how it isnt all that necessary to our survival however when we dont sleep our bodies produce some sort of substance that forces us to sleep. They have taken the blood from sleep deprived mice and put it in well rested mice and the well rested mice went to sleep. He explains how there are people today who only require 2 or 3 hours of sleep a night.
